STM32H750 Multifunctional Development Board

This is a multi-functional development and learning board based on the STM32H750. It's used for my personal learning of embedded hardware and software, integrating various strange and unusual functional modules. Basic functions have been verified. Further improvements will be made to various functions based on the board, and the board's support code will be continuously updated.

Function 1: Brushless motor drive module (function verified). A three-phase brushless motor driver based on the EG2133; using TIM1's CH1, 2, and 3 for 3PWM mode driving.

Three-phase current detection uses INA199 A2, 100x amplification, high-side current sampling (function verified).
The position sensor uses an AS5600 module (function verified )
 
. Updated 2024.6.30: Onboard touch sensor verification, onboard AS5600 position sensor verification, onboard EC11 rotary encoder verification;
learning of 3 interactive control methods for embedded development boards;
 
5-channel touch sensor (function verified).
The touch chip uses 5 single-channel sensors, 4 of which are set as synchronous outputs and 1 as a latched output.
PS: A video verifying the use of the touch buttons is attached.
 
The EC11 rotary encoder (verified)
is connected to the encoder interface of the STM32 TIM3; it has external pull-up and capacitor filtering.
